The wave glider is divided into a water surface boat and an underwater gliding propeller, the middle of the water surface boat and the underwater gliding propeller are connected by a flexible umbilical cable, the water surface boat drives the underwater gliding propeller to move up and down along with the wave, and hydrodynamic force fins arranged on the underwater gliding propeller generate a certain attack angle when moving up and down. The vertical water flow generates a horizontal component when passing through the wing with the attack angle, the water flow with the horizontal component has a horizontal reaction force on the wing, and the propeller advances by the reaction force of the water flow and finally drags the surface boat to advance.

And the wave glider is in vibration work for a long time, and has the requirement of vibration resistance on the design). Noise that spacing axle of fin and stop device rigidity collision arouses also can cause great interference to the sound mission load of wave glider, causes great startle to the marine organism of required research, also makes wave glider become very big noise source simultaneously, makes its disguised greatly reduced, influences the normal development of research activity.

However, since these parts are affected by seawater corrosion, high sea state wave impact, and the like when they are operated in seawater for a long time, they need to be replaced or maintained after a long time of operation. Present design adopts whole hydrodynamic force fin and the global design of gliding propeller lug connection under water basically, will carry out whole disassembling to gliding propeller under water when certain spare part wherein needs to be changed, the operation is complicated, and it is higher to the maintenance personal requirement, need maintenance personal to be familiar with the structure and the assembly process of whole gliding propeller and just can effectively accomplish the maintenance and not additionally damage whole gliding propeller, and maintain using the scene (like marine) under many circumstances, the site environment is complicated, the operation degree of difficulty of maintaining has further been increaseed.

During underwater operation, the rotating shaft 12 keeps rotational freedom with the mounting base 3 through a bearing, the rotating shaft 12 provides rotational support for the wing piece 1, the wing piece 1 is pushed by water flow to rotate around the rotating shaft 12, and the limiting shaft 13 swings in the limiting hole 14 during the process. When the maintenance fin 1 needs to be replaced, the corresponding module is directly taken down from the main frame to be replaced, the operation is simple and convenient, the operation personnel does not need to have higher technology, and the operation personnel does not need to know the structure inside the module, so that the maintenance and replacement time is shorter. The modular design also reduces the size of the workpiece, and reduces the material cost and the processing technology requirement.

In normal use, the high-strength spring 26 is additionally arranged in the rotation direction of the wing piece 1, so that the upturning angle and the downturning angle of the wing piece 1 can be automatically adjusted according to different stress conditions. When the underwater gliding propeller rapidly ascends or descends in a high sea state, the hydrodynamic wing panel 1 is impacted by rapid vertical water flow and receives water flow resistance in the vertical direction, and the limiting shaft 13 of the wing panel 1 compresses the high-strength spring 26. The spring 26 is compressed to cause the limit point to move upwards (the wing piece 1 turns upwards) or downwards (the wing piece 1 turns downwards), the upward-turning angle of the hydrodynamic wing piece 1 is increased when the limit point moves upwards, the downward-turning angle is increased when the limit point moves downwards, and the upward-turning or downward-turning angle of the wing piece 1 is increased to reduce the projection area in the vertical direction, so that the water resistance of the wing piece 1 in the vertical direction is also reduced, and the resistance of the water flow in the vertical direction is equal to the resilience force of the spring 26 to achieve balance. Taking the wing 1 as an example, when the wing 1 turns down, the limiting shaft 13 starts to compress the spring module 17, the initial turning-down angle 24 of the wing is 25 degrees, namely the turning-down starting angle of the limiting shaft 13, and the buffering turning-down angle 25 of the wing is 85 degrees, namely the maximum turning-down angle of the limiting shaft 13. The force applied to the wing 1 is different corresponding to different sea conditions, the harsher sea condition is the worse the wing 1 is turned down, and the vertical force applied to the wing 1 when the turning down angle reaches the maximum angle is F × cos (85 °), wherein F is the vertical force applied to the wing 1 when the wing 1 is horizontal. Compared with fixed-angle tab 1 perpendicular force F · cos (25 °) without spring modules 17, F · cos (85 °)/F · (25 °) approximately 10%, the force applied to tab 1 at the maximum angle was approximately 10% of the fixed angle, and the force was reduced by approximately 90%. Compared with the fixed-angle hydrodynamic fin 1 method, the design reduces the stress of the fin 1, the connecting shaft, the umbilical cable and the surface boat in high sea conditions, and reduces the damage of the high sea conditions to the components.

In example 2, in this example, the flap cushion upturn angle 22 is 25 °, the flap initial upturn angle 23 is 10 °, the flap initial downturn angle 24 is 15 °, and the flap cushion downturn angle 25 is 90 °.

In example 3, in this example, the flap cushion upturn angle 22 is 28 °, the flap initial upturn angle 23 is 12 °, the flap initial downturn angle 24 is 22 °, and the flap cushion downturn angle 25 is 80 °.

The overturning attack angle of the hydrodynamic airfoil 1 can be adaptively adjusted under different sea conditions. Under the better condition of sea condition, the underwater gliding propeller moves up and down slowly, and the water resistance of the fin 1 in the vertical direction is smaller, so that the overturning attack angle of the fin 1 is also small, and the small attack angle can generate larger horizontal component thrust, thereby being beneficial to the wave glider to capture weak wave energy and enabling the wave glider to obtain the maximum advancing speed under the condition of smaller sea waves. Under the condition that sea conditions are poor, the up-and-down movement speed of the underwater gliding propeller is high, and the water resistance in the vertical direction on the wing pieces 1 is increased, so that the overturning attack angle of the wing pieces 1 is also increased, and the water resistance in the vertical direction of the wing pieces 1 can be reduced by a large attack angle. According to theoretical analysis, the single wing 1 of the hydrodynamic wing 1 designed by adopting the traditional fixed attack angle is subjected to water resistance of more than 70kg under extreme sea conditions, and the total stress of the wave glider adopting 12 wings 1 can reach more than 800 kg. In addition, the impact force generated when the underwater gliding propeller moves up and down, so the large stress puts high requirements on the design, the process and the materials of the wing pieces 1, the water surface boat body and the umbilical cable. By adopting the design of the self-adaptive hydrodynamic wing panel 1, the attack angle of the wing panel 1 reaches the maximum under the most extreme sea condition, and compared with the design of a fixed attack angle, the maximum attack angle can reduce the water resistance by 90 percent, effectively reduce the stress of the wing panel 1, an umbilical cable and a surface boat, and reduce the requirements of the design, the process and the material of each part.

The modular design of the self-adaptive hydrodynamic fin 1 facilitates installation, maintenance, replacement, transportation and storage of the whole machine, the split base design of the self-adaptive hydrodynamic fin 1 module reduces the base processing difficulty, and the production and processing cost is also reduced. The wave glider adopting the modularized self-adaptive hydrodynamic fin 1 is already put into use, and the design effectively improves the survival capability and the long-time working capability of the wave glider under the high sea condition and reduces the working noise.
